Objective: The aim of the present study was to evaluate the efficacy of Passiflora incarnata L for the control of anxiety during third mandibular molar extraction and compare it to midazolam, the most used benzodiazepine in dentistry.
Method and materials: The investigators implemented a prospective, randomized, double-blind, split-mouth study. The degree of anxiety of the patients was assessed before the surgical procedure. The surgeries took place in two sessions: one on each side of the hemi-mandible and, on each of them, the patient received one of the drugs, crosswise. Anxiety control was measured through physical parameters, at the following periods during the surgery: (1) immediately administration of anxiolytic medication, (2) 30 minutes after anxiolytic medication, (3) after extraoral antisepsis, (4) after local anesthesia, (5) during incision, (6) during osteotomy, (7) between osteotomy and odontosection, (8) during odontosection, (9) during surgical store curettage, (10) during suture, and (11) immediately after postoperative care guidelines. Lastly, the volunteers received a self-assessment form in order to report their experience. Statistical analysis was performed using the Wilcoxon test.
Results: The final sample was composed of 20 patients, with a mean age of 22.5 years. The results of the physical parameters showed statistically significant differences (P < .05) for certain times and physical parameters, especially heart rate (P = .036), which showed the highest control for Passiflora at time point (3). The undesirable effects reported by patients such as drowsiness, muscle relaxation, and dizziness were greater with benzodiazepine.
Conclusion: The results of this study suggest that Passiflora may be considered as an alternative to midazolam in controlling anxiety in dentistry. Future studies will focus on other benzodiazepines and herbal medicines.
